- A Host devices tab on the VM page lists the VM's USB host devices, each once: how it is chosen (its address, or any device of its model), the device the running VM holds and whether its next start has it; its other host devices (PCI, SCSI, mediated) are listed for the XML editor. - Superusers add a USB device of the host and take it back, on a running VM too. The add form is loaded when the tab opens, as its choices read every VM of the host; a hub, a device the host has its own disks or network interfaces on, or one another VM names is not offered, with the reason, and refused on the server under the compute's claim. A device is chosen by model when the host has one of it, else by its address. - A VM without a USB controller is refused; a device is taken from each definition as that definition describes it. - A clone gets none of the VM's host devices (the clone form says so), and a VM with host devices is not migrated. A snapshot revert is refused when it would give the VM a device another VM names or the host uses. - A NIC that is a host device is no longer edited or removed from the Network tab: the XML editor changes it.
